Garrison

A Garrison is a place where an army is recruited to defend a city. It is here that resources are used to train soldiers for the city's armies. While there are no requirements for building a Garrison, additional skills and buildings are required to train soldiers other than Halberdiers. Higher levels of Garrison increase army training speed.

The tooltip (when the mouse is moved over the symbol) only says "increased by PERCENT%%", however, recent data analysis revealed that it was 2% per level, excluding level 1. This bonus is added to the conscription bonus, and not taken off before or after. For example, a conscription skill of 2 and a garrison at level 2 gives a 6% reduction in training time. Increasing either level by one will yield a 2% higher bonus.

You can build multiple Garrisons in the same city, which will allow you to train troops more quickly (for example, training 1000 Archers would take a base time of 08:20:00 in one Garrison but only 02:05:00 if you trained 250 Archers in each of four Garrisons).
